DETACHABLE BOOK-COVER.

SFEOIFIGATION forming part of Letters Patent No. 691,731, dated January21, 1902.

Application filed March 11, 1901. Serial No. 50,669- (No model.)

To all whom it may concern.- I

Be it known that I, GUSTAV ADOLPH ROEDDE, a citizen of the Dominion ofCanada, residing at Vancouver, in the Province of British Columbia,Canada, have invented a new and useful Temporary Binder, of which thefollowing is a specification.

This invention relates to improvements in that class of temporarybinders adapted to be held within cover members to be used for holdingmagazines or papers; and it primarily seeks to provide an appliance ofthis character capable of being held within the cover members in suchmanner that it cannot be readily removed therefrom and which will affordevery convenience for handling the papers or books held thereby and inwhich the said papers and books will be retained in good condition for asubsequent permanent binding; and the said invention consists in thenovel construction and peculiar combination of parts hereinafter fullydescribed, and particularly pointed out in the appended claims,reference being .had to the accompanying drawings, in which- Figure 1 isa perspective view of the cover member opened out and the holder securedthereon, one of the binder-bars being in a raised position, the hingedkeeper of the lock member being also shown thrown back. Fig. 2 is adetail View of one of the binder or lock bars. Fig. 3 is a cross-sectionof the casing or box and the lock-bars held therein, and Fig. 4 is aview illustrating my invention as in use.

In the drawings, in which like characters indicate like parts in all thefigures, 1 designates an oblong metal casing having a length and widthto suit the thickness of paper or magazine to be held thereby and alength approximately that of the cover 0, and at the ends at its base ithas extensions l adapted to be bent over the edges of the flexible part0 of the cover and to form locking-clamps 1 to secure the casing on thecover, as clearly shown in Figs. 1 and 4, whereby to securely hold thecasing on the cover and-prevent its being easily detached oraccidentally separated therefrom.

At one end the casing 1 has a transverse pin 2, and at the opposite edgeit has a springlock 4, the upper face of which lies in a plane bars hasa quarter-twist to cause its end to lie.

in a plane at rightangles to the body, and said end is turned to form aneye 3 to engage the pin 2 to permit the lock-bar swinging upon avertical plane, as clearly shown in Fig. 1, and the opposite end of thebars is also formed with a quarter-turn-to produce a fiat extension 3adapted to lie flatwise upon the flat upper face of the lockv 4,-whichincludes a hinged keeper 5, adapted to close down over the flat ends3*of the bars 3 when it is swung down to its locking position, as shownin Fig. 3, and to facilitate the lifting of the bars 3 when unlockedsaid ends 3 terminate in headed portions 3", that project beyond theouter end of the look, as clearly shown in Fig. 4.

From the foregoing description, taken in connection with the drawings,it is thought the manner of operating and the advantages of my inventionwill be readily understood.

It will be noticed the papers or magazines cannot be removed from thecasing or holder without unlocking the" bars 3, and the casing will notreadily become detached from the cover by reason of theclamps 1.

I am aware that box-like members capable of being secured to a' coverand having locking-bars disposed longitudinally thereon have heretoforebeen provided. My invention differentiates, so far as I know, from whathas heretofore been provided in this line in the peculiar correlation ofthe casing with the cover, the axial pin in one end, the lock having aflat top at the other, and the peculiar form of lock-bars that cooperatewith the axial pin and the lock.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. A temporary binder, comprising in combination with a book-cover, aU-shaped casing extended lengthwise of the foldable part of the cover,said casing having extensions 1, at the opposite ends adapted to clampover the edges of the cover, locking-bars, pivotally mounted in theupper edge of one end of the U-shaped casing to swing in a verticalplane, a lock 4 in the opposite end of the casing, said lock including aflat bearing-surface, and a hinged keeper adapted to close down oversaid flat bearingsurface, the locking-bars having their free endsflattened to flatwise engage the said flat surface of the lock, allbeing arranged substantially as shown and for the purposes described.

2. A temporary binder, comprising in COlIlbination, with a book-cover, aU-shaped casing extended longitudinally on the foldable part of thecover, lockingbars pivotally mounted on one end of the casing to swingGUSTAV AD OLPI-I ROEDDE.
